| Volatile Memory |
Memory that loses its contents when the power is turned off. A computer's main memory, made up of dynamic RAM or static RAM chips, loses its content immediately upon loss of power. Contrast ROM, which is non-volatile memory. |
| VRAM |
(Video RAM) VRAM has two separate data ports. One is dedicated to updating the image on the screen while the other one is used for changing the image data stored in memory. This "dual-ported" design gives higher performance than DRAM which cannot read and write simultaneously but is more expensive. |
